My idea to help curb road rage and improve driver behaviour.

A small LED strip mounted inside rear window of the car.

It would be Bluetooth-linked to a panel that could be mounted on the console with buttons that trigger brief flashing messages on the LED screen.

• THANKYOU!
• APOLOGIES!
• THANKS FOR LETTING ME IN.
• etc etc.

Obviously this idea could be subverted to generate negative messaging…but that would just be a dick move.

Giving positive feedback on the road. It’s a simple thing that could make a difference.

Does such a device already exist? Could someone build it for me?
